You can access the group and example options from within an example:
describe "group options hash", :defined_in => :group do
it "is available in examples via self.class.options" do
self.class.options[:defined_in].should == :group
describe "example options hash" do
it "is available in examples directly", :defined_in => :example do
options[:defined_in].should == :example
